DIESEL-RK is an engine simulation software. Simulation and optimization of combustion and mixture formation in diesels.

Nitrogen oxides NO, soot and particles formation modelling. Common Rail control algorithm development. Turbocharging, supercharging, EGR. Thermodynamic analysis.

LOTUS ENGINEERING SOFTWARE (LESOFT) Computer simulation is a key part of the automotive development process. Lotus Engineering Software has been developed by automotive engineers, using them on many powertrain and vehicle projects at Lotus over the past 20 years. Lotus Engine Simulation Software Free is a collection of products with 90 downloads. The most lightweight of them are PID (sized at 39,582) and Digital Logic Simulator (sized at 400,372), while the largest one is Falcon BMS with 944,760,059 bytes.

Valve timing optimization. Bauman Moscow State Technical University (BMSTU). Download Simulation kernel has been updated recently. Now for the it is possible to use version 4.3.0.189 (Oct. Previous version of DIESEL-RK is not supported now Data files being used in previous version 4.1.3.143 of the DIESEL-RK are supported by version 4.3.0.189, but some mismatch is possible. In the case of problem, please contact with support team. Do not forget to attach a problem data file to message.

Simulation server is available now at srv1.diesel-rk.bmstu.ru Combustion and other models were improved so simulation data of new DIESEL-RK may differ from previous results. Check duration of combustion in results of simulation. If this value looks incorrectly, calibrate factor 'y' in the equation of evaporation rate in diesel.

Last Local version of the DIESEL-RK is 5.3.2.23 (October 2018). Differences between the versions 4.3.0.189 and 5.3.2.23 is presented.

If you want to use DIESEL-RK under non-administrator account the correct installation steps are: 1. Install DIESEL-RK under account with administrative privileges. Don't install software to default location (i.e. 'C: Program Files Diesel-RK Net'), install to 'C: diesel-rk' or 'D: dieselrk', etc. Set permissions for the installation folder to grant users 'Read/Write/Execute' access. File for download. Size Description, date 20.8 Mb Distributive package of Client part of DIESEL-RK software.

** - Slides only. To get started create a new project and and follow 'Wizard of New Project Creation'. The Wizard creates new data file with typical engine specification being nearest to your data. Save data file and run simulation for testing. Modify the data file corresponding with details of your engine design and operating parameters. Run Simulations / Scanning / Optimization. To plot graphs Drag-and-Drop functions from Tree View on the left panel to Diagram area.

In the late versions of DIESEL-RK the developers implemented special abilities for users to develop own User Models for different physical phenomena as Dynamic Link Libraries (DLL). Now DIESEL-RK has special interface to link User Models and set data for them. The examples of FORTRAN sources for all kinds of User Model DLLs are presented in the distributive kit. List of innovations of version 5.3.2. 23 (2018) in comparison with 4.1.3.

143(2008) • Link with the User Model DLL intended for Friction Pressure simulation. This function is useful for users having rich experimental data about engine mechanical losses. • Link with the User Model DLL intended for Complex Emission calculation. This function is useful for users dealing with engine emission reduction problem, when it is necessary to decrease SFC, NOx and Soot simultaneously. • Link with the User Model DLL intended for Ignition delay prediction.

This function may be useful for users dealing with PCCI and HCCI engine analysis, as well working with bio-fuels. • User can select Different models for Ignition delay prediction. It becomes possible to compare results obtained with different methods. It is actual for PCCI research.
